So, in Figure 30, Figure 31 and example shown in Figure 32, confirm the participant etc. of strong point E after, authentication is participated in.Therefore, guarantee fail safe.

And, also can be that strong point B represents strong point B, strong point C and strong point D, authenticates strong point E.For example, strong point B is behind authentication strong point E, to the transmission permission of strong point C notice image data and voice data.In view of the above, the network sending part 1411 of strong point C after the participation of strong point B authentication strong point E, will send to strong point E at the image that strong point C takes.That is to say that strong point E behind blanket property ground authentication strong point B, can always carry out communicating by letter with the video conference at each strong point with both sides.

As mentioned above, according to embodiment 1, to transmitting inherited information as the strong point E that inherits the destination, strong point E is connected with video conference system as the strong point A that inherits the source.In view of the above, the video conference system among the embodiment 1, the state of the video conference that can keep carrying out so far carries out the succession of video conference.

And, become at strong point A under the situation of server, by server capability being inherited strong point B, thereby also can proceed video conference.And then strong point A carries out based on the notice that connects the strong point change, and the strong point reflection that receives notice connects the change at strong point, thereby in the video conference system that the needs authentication is participated in, also can proceed video conference.

And the strong point E that inherits can keep strong point A according to the state of connection line and determined coding method begins coding.In view of the above, the user of video conference system can omit according to the state of connection line and adjust this labour of coding method.

And, inherit the strong point E of destination, the picture that can keep the strong point A in succession source constitutes, and does not also change the picture formation by reconnecting, and can proceed video conference with the condition identical with strong point A.

And, continue strong point B, strong point C and the strong point D of participating television meeting, inherit the strong point E of destination by position display at the strong point A in the source of succession, thus can be in identical position display identical participant.In view of the above, do not change picture and constitute, can proceed video conference yet.

And, connecting the information of the address of destination for expression, the typical case utilizes the IP address, but (the Media Access Control: medium access control) address that also can utilize MAC.Connect strong point management department, utilize these address informations, also can authenticate the participating television meeting.And, substitute address information, and can utilize the information that is used for determining each TV conference apparatus.For example, for the information that is used for determining each TV conference apparatus, can utilize the unique identifier as the serial number of each TV conference apparatus etc.

And, also can be, not via network, and via the storage medium of storage card etc., exchange inherited information.According to these methods, be under the situation of power supply disconnection also at the strong point of inheriting the destination, can keep inherited information as set information.

And, for inherited information, also can be, not only when inheriting, utilize, also be used in keeping of set information.That is to say, be not limited only to inherited information is applicable to the strong point E that inherits the destination.For example, also can be that the user that strong point A has participated in video conference, after temporarily leaving a banquet or a meeting from video conference, under the situation of strong point A participating television meeting, inherited information is applied to strong point A once more.

And, in the inherited information, except comprising example shown in Figure 20, can also comprise the information that is switched on or switched off that OSD (On Screen Display: show at screen) shows.And, can comprise display position, display size in the inherited information and show ratio, to constitute as picture from the image at each strong point.

And, also can be that the network sending part or the network acceptance division of each TV conference apparatus are replaced into, with the sending part or the acceptance division of wireless wireless transmission part that communicates or wireless receiving portion etc.And, also can be that each TV conference apparatus carries out video conference communication and inherits processing with wireless.

And, also can be, the succession configuration part 1324 of TV conference apparatus 1300, under the characteristic of the picture of the physical property of TV conference apparatus 1300 situation identical with the characteristic of the picture of the physical property of TV conference apparatus 1100, the picture that utilizes inherited information to set TV conference apparatus 1300 constitutes.

At this, for example, the characteristic of the picture of physical property is to have influence on the characteristic of the picture formation of the aspect ratio of picture or the size of picture etc.Under the different situation of these characteristics, sometimes, before succession with inherit after, picture constitutes different.On the contrary, under the identical situation of the characteristic of the picture of physical property, picture constitutes to be inherited exactly.When the TV conference apparatus of destination is inherited in authentication, confirm whether TV conference apparatus is corresponding equipment, thereby whether the characteristic of picture that also can confirm physical property is identical.
